Las Vegas police Capt. Vincent Cannito said Stiles has been wanted since Oct. 5 on warrants issued for 21 felony charges in connection with the acts seen on the videotape. The charges include lewdness with a minor, sexual assault and attempted sexual assault.

Hunt for abused girlThe videotape, found in the rural Nevada town of Pahrump last month, had prompted an equally intense search for the young girl who appeared in it. Police with little to go on had encouraged news organizations to broadcast the haunting image of the 3-year-old. When the now-7-year-old was found on Sept. 28, authorities shifted their resources to finding Stiles.

Dye said he stopped Stiles at about 7 p.m. on a busy thoroughfare just outside Las Vegas driving a white sedan with no license plates.

Stiles, who had been portrayed by authorities as a dangerous, knife-wielding survivalist, provided an expired California driver's license with a photo that Dye said looked "suspicious."

"The picture on the license didn't quite match the gentleman in the vehicle," Dye said.

After further questioning, the officer said Stiles revealed his true name. Dye said Stiles cooperated and did not resist arrest. Dye called for backup and another officer arrived to handcuff Stiles.

Stiles was booked at the Clark County jail. He had not yet hired a lawyer or been assigned a court date, police said.

Previous warrantsStiles was already wanted on state and federal warrants in a case alleging he groped a 6-year-old girl in 2003. Police had received hundreds of tips on Stiles, who they believed might be dangerous and possibly armed based on earlier arrests.

Stiles' previous arrests included charges of assault, battery, resisting a police officer, auto theft, leaving the scene of an accident and contempt of court, authorities said.

He was convicted in 1999 in Las Vegas of carrying a concealed weapon, and in 2001 of conspiracy to commit grand larceny. Police were also looking into an allegation that he had sexually assaulted a young girl in 2001.

Nye County District Attorney Bob Beckett had said he was told Stiles was a "survivalist type" who always carried knife and had a Navy SEAL background.

The man who turned in the videotape, Darrin Tuck, 26, was arrested on a probation violation charge, and was likely to face pornography charges, Beckett said.
